rpmsg: glink: Release driver_override 

[ Upstream commit fb80ef67e8 ]

Upon termination of the rpmsg_device, driver_override needs to be freed
to avoid leaking the potentially assigned string.

Fixes: 42cd402b8f ("rpmsg: Fix kfree() of static memory on setting driver_override")
Fixes: 39e47767ec ("rpmsg: Add driver_override device attribute for rpmsg_device")
